RAILROAD FROG OR CROSSING.

SPECIFICATION forming part of Letters Patent No. 554,911, dated February 18, 1896.

Application filed October 5, 1895. Serial No. 564,757. (No model.)

we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

This invention relates to certain improvements in railroad frogs or crossings.

The object of the invention is to provide a railroad frog or crossing exceedingly simple, durable and economical in construction, which shall be composed of a minimum number of parts, and can be easily and economically manufactured and the parts assembled where the frog or crossing is to be located, if so desired.

The invention consists in certain novel features of construction and arrangements of parts more fully described hereinafter and particularly pointed out in the claims.

Referring to the accompanying drawings, Figure 1 represents the improved frog 0r crossing in perspective. Fig. 2 represents the parts of the frog separated and in perspective, the clamping-bolts not being shown.

In the drawings the frog or crossing is shown composed of two rails, bent V-shaped or with diverging ends, one rail at its apex having an outward offset or deflection to receive the apex of the opposite rail. Ablock is interposed between the rails at their meeting central portions so as to rest beneath the heads or treads of the rails. This block is suitably bent to fit the inner sides of the rail and the securing-bolts passed through the block and the rails.

a is the rail, which is bent V-shaped to the proper angle and which forms one side of the frog or crossing and which forms portions of the two opposite tracks. In this particular frog shown a is the right-hand rail.

1) is the opposite left-hand rail having its two ends diverging at the same angle as the ends of rail a and forming the opposite side of the frog and continuations of the two legs of the rail a. At its apex the rail bis deflected outwardly to form a socket or recess 1) at its inner or engaging side to receive the apex of the rail a, and this lateral deflection is preferably of such a depth or degree as to permit the apex of the rail a to fit therein such a distance that the two legs of the rail to will be exactly aligned, respectively, with the two legs of the rail 1). The bottom flanges of these two rails at or about their meetingpoints can be cut away, and the block b can be interposed between the rails and beneath the heads or treads thereof, so as to fit the webs of the rails and the heads thereof, the block being suitably formed to. conform to the curves or bends of the rails at these points.

01 are the clamping-bolts, any suitable number being employed, which are passed through the webs of the rails and said block to properly secure the frog by rigidly clamping the rails and block together.

The respective legs of the frog-rails being aligned, groove 01. is planed or out diagonally across the top of the heads or tread of rail a and in alignment with the inner edges of one leg of rail a and the corresponding opposite and aligned leg of rail 1) for the flanges of the wheels passing along said two legs.

Groove d is cut or planed diagonally across the deflected portion of rail 6 to receive the flanges of the wheels passing along the opposite leg, the two grooves just described forming a V.

It is evident that various slight changes might be made in the forms, constructions, and arrangements of the parts described without departing from the spirit and scope of our invention. Hence we do not wish to limit ourselves to the exact construction herein set forth, but consider ourselves entitled to all such changes as fall within thespirit and scope of our invention.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent of the United States, is
